Men's testosterone levels naturally decline as they get older. This has a number of detrimental effects, including decreasing energy levels, diminished sex drive, and loss of lean muscle mass. Many men turn to testosterone supplements to help them regain their vitality and improve their muscle-building potential.
Two of the most well-known testosterone boosters on the current market are TestoPrime and Prime Male. So, which is the best? To help you choose between these two leading contenders, we compare the ingredients, potency, and overall value of TestoPrime and Prime Male in this head-to-head comparison.
Both TestoPrime and Prime Male are quality testosterone boosters. If they weren't, they wouldn't sell in the quantities they do. Both contain a dozen ingredients that, on the whole, have some pretty solid research behind them.
However, the ingredient profile of TestoPrime ticks off more of the ingredients that are universally accepted as base 'T' booster ingredients, including fenugreek, ashwagandha, D-AA, and zinc. The dosages in TestoPrime are also a little higher than you find in Prime Male.
As a result, though it's a close comparison, we give TestoPrime the slight edge in terms of overall effectiveness as a natural testosterone-boosting supplement.
TestoPrime is a natural testosterone-boosting supplement that was created to support men in optimizing their hormone levels and enhancing their general health and wellness. It is manufactured by Wolfson Brands, a UK-based business specializing in creating premium dietary supplements. TestoPrime is manufactured with premium-grade natural ingredients in GMP and FDA-approved facilities.
The dozen active ingredients in TestoPrime include D-aspartic acid, ashwagandha, fenugreek, and zinc. The formula is designed to increase testosterone levels, help with body recomposition (more muscle and less fat), increase energy levels, boost cognitive ability, and enhance cell health.
Other products manufactured by Wolfson Brands include PhenQ, NooCube, and Testo-Max.
TestoPrime has established itself as a market leader in the natural testosterone booster market, with thousands of positive reviews online. Here is a typical example:
"Since I've been taking TestoPrime I definitely have more energy to play with my kids, am less stressed and I feel much happier in myself. This supplement is a game-changer."
- Matthew Clarke
Prime Male is manufactured by Roar Ambition, a UK company that puts out a range of popular weight loss and health supplements, including Instant Knockout, Hourglass Fit, and Testofuel, which is another testosterone booster. While Testofuel is more geared toward the bodybuilding market, Prime Male is marketed toward men over the age of 40.
Among its twelve ingredients, Prime Male contains a number of compounds that are common with TestoPrime. Unique ingredients in Prime Male are magnesium, luteolin, nettle root, boron, and Vitamin K2. This product can only be purchased from the official website.
The key spokesperson for Prime Male is action movie star Hollywood legend Dolph Lundgren.
As with TestoPrime, there are a lot of reviews for Prime Male to be found online. Here is a sample review:
"IMPRESSIVE!!! I'm glad I found this product. I have had shoulder and back issues for several years which made it difficult to get active again. After having my blood work, I discovered Testosterone levels were low, so after 2 years of injections with minimal results, I needed to find something that worked better with less hassle and a safer alternative. I found it in Prime Male. My active energy and endurance have greatly improved with no negative side effects, even getting through my work shifts was a struggle and now I can function with far more energy. I have improved my body composition with no changes in diet or additional fitness programs."
Rick Erickson, USA
TestoPrime contains a dozen completely natural ingredients that are designed to up the body's natural production of testosterone and produce other health benefits. Here's an overview of each of them, along with references to the science on which its claims are based.
D-aspartic acid (D-AA) is an amino acid that is involved in the production of hormones in the body, including testosterone. Studies have shown that D-AA increases the pituitary gland's output of luteinizing hormone (LH), which stimulates the testes' Leydig cells to produce more testosterone.¹
There is also research suggesting that increased fertility may result from D-AA. Studies suggest that in men with low sperm counts, supplementation of this amino acid may boost sperm quality and fertility. An increase in male sex drive and performance, which are significantly impacted by testosterone, has also been shown to be possible with D-AA supplementation.²
The dosage of D-AA used in most studies is between 2.6-3 grams.³
Panax ginseng, commonly called Asian ginseng, belongs to the Araliaceae family of plants. It has long been used in traditional medicine to increase vigor, brain function, and general well-being. This is one of many traditional ingredients that have seen a surge in recent times for their performance enhancing effects.
Panax ginseng has been linked in certain studies to possible advantages for testosterone boosting due to its ability to raise levels of luteinizing hormone (LH), which increases testosterone production in the testes.⁴
According to a study that was published in the International Journal of Impotence Research, Panax ginseng extract significantly increased blood testosterone levels and erectile function in males with erectile dysfunction.⁵
Although there is encouraging evidence that Panax ginseng can increase testosterone levels, more studies are required to establish its long-term safety and efficacy and the ideal dosage and duration of consumption.
Ashwagandha, or Withania somnifera, has been employed in conventional medicine for centuries to reduce stress, enhance brain function, and increase energy. Ashwagandha supplementation has seen a surge in recent history, due to it's positive benefits.
KSM-66 is a standardized extract of the root of the Ashwagandha plant, which contains a higher concentration of withanolides, the active ingredients in ashwagandha thought to be responsible for its possible health benefits, such as helping lower blood pressure.
KSM-66 Ashwagandha extract has been demonstrated to raise levels of luteinizing hormone (LH), increasing testosterone production in the testes.⁶ A KSM-66 Ashwagandha extract intake for eight weeks led to appreciable gains in muscle growth, strength, and testosterone levels in healthy males, according to a study that was published in the Journal of the International Society of Sports Nutrition.⁷

Fenugreek is a medicinal plant with a long history of use in Africa and India for treating a wide range of ailments. In recent years, it has undergone study for its claimed ability to boost testosterone levels. The active compound in this regard is furostanolic saponins, which may boost natural testosterone production in the testes.
An 8-week study that was published in the Journal of the International Society of Sports Medicine reported that 500 mg of fenugreek daily was able to significantly increase serum testosterone levels in healthy men, as well as improve their strength and reduce their body fat levels, compared to a placebo group.⁸

By delaying the conversion of testosterone to dihydrotestosterone (DHT), green tea extract may be able to increase testosterone levels. DHT is a testosterone byproduct known to contribute to the growth of masculine features but has also been connected to hair loss and enlarged prostates.
The enzyme 5-alpha reductase transforms testosterone into DHT. Green tea extract is believed to enhance testosterone levels in the body by decreasing the quantity converted to DHT by obstructing this enzyme.
Green tea also contains a number of bioactive compounds that might have antioxidant and anti-inflammatory properties and may suppress brain aging.⁹
Pomegranates have been shown to provide various health benefits, like improved cardiovascular health, reduced inflammation, and a lower risk of various malignancies. That is largely because they provide a rich source of antioxidants.
Claims that pomegranate extract may enhance male testosterone levels are not well supported by the available research.¹⁰ However, it has been shown to enhance blood flow, resulting in enhanced nutrient and blood supply to the working muscles. This may improve endurance and offset training fatigue when working out.¹¹
Vitamin D is produced by the body from exposure to sunlight. Many people, though, do not get enough of it, which is why vitamin D supplementation can be important. This essential nutrient is involved in bone health and immune function. There is some research to suggest that vitamin D has the ability to improve testosterone levels, though the exact mechanism is unclear.¹²
Vitamin D may boost the production of hormone (LH) and follicle-stimulating hormone (FSH), which are hormones that control testosterone production in the testes.
Another possibility is that testosterone levels may rise as a result of improved insulin sensitivity brought on by vitamin D. Last but not least, inflammation has been associated with reduced testosterone levels, and vitamin D may assist in alleviating it.
Zinc is an essential mineral directly involved in testosterone production in the testes. Studies have shown that supplementing zinc can significantly increase 'T' levels and that low zinc levels are associated with low levels of testosterone.¹³
Zinc has also been shown to improve sperm quality and libido in men.¹⁴
Vitamin B6, or pyridoxine, assists in the metabolism of amino acids as well as the production of such neurotransmitters as serotonin, norepinephrine, and dopamine. Research shows that taking B6 can increase testosterone production in men with low levels. This is believed to be due to its ability to promote the release of the transmitters dopamine, norepinephrine, and serotonin, which are involved in the regulation of the hypothalamic-pituitary-gonadal axis (HPG axis), the pathway that regulates testosterone production in the body. Vitamin B6 may increase testosterone levels by regulating the activity of the HPG axis.¹⁵
Vitamin B5, or pantothenic acid, is crucial for a number of biological processes. It contributes to the synthesis of fatty acids, cholesterol, and hormones, as well as the release of neurotransmitters and the generation of energy from meals. It has also been demonstrated that vitamin B5 is good for male reproductive health and testosterone production.
Studies have shown that vitamin B5 supplementation can raise testosterone levels in men who have low levels of the hormone since vitamin B5 is involved in the production of testosterone.¹⁶
The following compounds contained in garlic may help improve testosterone levels:
In a rodent study, rats that were given garlic extract for 28 days had significantly increased serum testosterone levels compared to those given a placebo.¹⁷
Other research suggests that garlic may be able to help lower cortisol levels.¹⁸ Testosterone and cortisol have an inverse relationship, so the higher a person's cortisol levels, the lower their testosterone levels will be.
Black pepper extract, also known as piperine, which is derived from the black pepper plant, increases the bioavailability and absorption of nutrients such as vitamins, minerals, and amino acids. It is included in Testorpime to increase the effectiveness of the other ingredients.¹⁹
Some of the dozen ingredients in Prime Male are the same as those in TestoPrime. In this section, we'll profile those that differ and contrast the dosages of the ingredients that the two products have in common.
D-aspartic acid calcium chelate is a version of the amino acid D-AA that is bound to a calcium ion. Through a process called chelation, it is believed that this improves the bioavailability and absorption of the D-AA so that it is more effective than the stand-alone version of the supplement.
There isn't much research comparing the effectiveness of D-AA and D-AA calcium chelate, despite the fact that both have been demonstrated to increase testosterone levels. While some studies have revealed no differences between the two forms, some have suggested that D-AA calcium chelate may be more effective at boosting testosterone levels and enhancing fertility.
Bioperine is Prime Male's alternative to the piperine in TestoPrime. It is included to enhance the bioavailability and absorption of the other ingredients. This is a patented form of piperine that has a standardized 95% piperine content.
Boron is a trace mineral boron, which is present in many foods in tiny amounts. Studies have indicated that boron may help increase the body's free testosterone levels. It is crucial for bone health and has been demonstrated to increase bone density and lower the incidence of osteoporosis. In addition, it has been shown to reduce inflammation in the body, which is vital for general health and well-being.²⁰
Although they are related, the Korean red ginseng in Prime Male and the Panax ginseng in TestoPrime differ slightly from one another. Panax ginseng is indigenous to China, Korea, and Siberia. On the other hand, Korean red ginseng is a kind of Panax ginseng that has undergone special harvesting, processing, and drying procedures in order to improve its therapeutic characteristics.
In order to boost the concentration of ginsenosides, the active ingredients in ginseng thought to be responsible for its potential health benefits, fresh Panax ginseng roots are steamed and dried several times over the course of several weeks to produce Korean red ginseng. The ginseng that results from this process is usually more expensive than regular Panax ginseng and is utilized in Eastern medicine for a variety of health issues, including as a natural testosterone booster.
There is three times as much ginseng in Prime Male compared with TestoPrime (120 mg vs. 40 mg).
Luteolin is a plant-based compound known as a flavonoid that is found in fruits and vegetables. It has been demonstrated that luteolin blocks the action of the aromatase enzyme, which transforms testosterone into estrogen. Luteolin may support men's healthy testosterone levels by blocking the enzyme aromatase.²¹
Luteolin contains anti-inflammatory characteristics and has been demonstrated in laboratory experiments to slow the growth of prostate cancer cells, supporting prostate health.
Magnesium is an important mineral that is important for more than 300 enzymatic processes, such as protein synthesis, neuron and muscle function, and blood sugar regulation. Magnesium has also been shown to be beneficial for male reproductive health and testosterone production.
Studies have shown that supplementing magnesium can raise testosterone levels in men with low levels of 'T' since magnesium is involved in the manufacturing of the hormone.²² Magnesium supplementation may also enhance physical performance and reduce muscular fatigue. In addition, magnesium is important in muscle and nerve function.
Mucuna pruriens is a tropical legume plant also known as velvet bean or cowhage. Traditional uses of the plant in Ayurvedic medicine include treating nervous system diseases, treating male infertility, and acting as an aphrodisiac.
Levodopa (L-DOPA), a precursor to the neurotransmitter dopamine, is present in high concentrations in the seeds of the Mucuna pruriens plant. Dopamine is necessary for the control of mood, drive, and sexual function. It also has an impact on testosterone production.
Some research shows that mucuna pruriens may help to boost natural testosterone production.²³
Stinging nettle produces nettle root extract from its roots. The active compounds are phytosterols, polysaccharides, and lignans. Nettle root extract might be able to increase free testosterone, the body's active form of the hormone, due to its ability to increase the body's supply of free testosterone by preventing the binding of testosterone to sex hormone-binding globulin (SHBG).²⁴
Vitamin B6 is another ingredient that is common to both products. The 7.5 mg in Prime Male is a full mg higher than in TestoPrime. Both levels are well above the NIH recommendation of 1.3 mg for adults.
Vitamin D is the third ingredient that is in both TestoPrime and Prime Male. The 4000 IU in Prime Male equates to 100 mcg, which is more than three times the amount in TestoPrime.
Fat-soluble vitamin K2 is essential for healthy bone development and blood coagulation.²⁵ Because it aids in the activation of proteins involved in the creation of bone tissue, vitamin K is crucial for bone health. Supplementing vitamin K may lower elderly men's risk of osteoporosis and fractures.
Zinc is common to both Prime Male and TestoPrime. However, Prime Male contains 10 mg less of it than TestoPrime. Both levels are higher than the recommended daily intake of 8-14 mg.
Wolfon Brands promote the following benefits of taking Testoprime:
By reducing cortisol levels, it is claimed that TestoPrime will reduce stress levels by as much as 71.6%
The increased testosterone levels from taking TestoPrime may be able to speed up the metabolism to help with fat burning.
A number of the ingredients in TestoPrime have research supporting their potential to boost libido and increase sexual performance.
The TestoPrime website claims that taking the supplement can increase muscle strength by up to 138.7% due to its testosterone-boosting ability.
A number of ingredients in TestoPrime are able to boost energy conversion from stored body fat. This is claimed to be able to increase fat conversion to energy by 12%.
The ingredients in TestoPrime may increase VO2 max by up to 92.2%. This supports higher nitric oxide levels for greater endurance.
Even though TestoPrime is considered to be a safe dietary supplement, there are some minor side effects that have been experienced by users. These include:
Allergic reactions, including hives, swelling, and breathing difficulty
Digestive problems such as diarrhea, constipation, and stomach cramps
It should be noted that most people will not experience any of these side effects and that there have not been any reported major side effects associated with this supplement.
Roar Ambition highlights the following five key benefits of taking their product:
A number of ingredients in Prime Male, including vitamin B6 and magnesium, may be able to increase the conversion of food into energy.
Higher testosterone levels may lead to greater muscle mass. This will, in turn, increase the metabolism and consequent calorie burn, leading to improved weight loss.
Certain ingredients in Prime Male, such as mucuna pruriens, may improve mental functioning, boost concentration, and help with memory.
Prime Male may increase endurance levels, boost cardiovascular health, and improve workout recovery.
A number of the ingredients in Prime Male have the research-backed ability to increase virility, boost libido, and enhance sex drive.
The following side effects have been experienced by Prime Male users:
Remember that these side effects are generally minor and rare. Prime Male is generally safe to use and has no known major side effects.
Wolfson Brands suggests that you take four capsules of TestoPrime about 20 minutes before breakfast.
Roar Ambition recommends that you should take four capsules of Prime Male per day. This intake should be separated throughout the course of the day, with each dose separated by three hours (i.e., 8 am, 11 am, 2 pm, 5 pm).
TestoPrime should be consumed with a glass of water. Prime Male should also be taken with water.
TestoPrime and Prime Male can both only be purchased from their official websites. They both offer discounts for multi-bottle purchasers, along with free shipping and a money-back guarantee.
Wolfson Brands offers free shipping on all purchasers. Your TestoPrime purchase is covered by a lifetime money-back guarantee. You also get access to free testosterone-boosting e-books.
Roar Ambition provides free shipping to the UK and the US. They also provide a money-back guarantee and free e-books (but only for multi-bottle purchasers).
Your particular needs and objectives will determine whether TestoPrime and Prime Male are worth it. These testosterone-boosting supplements might be worth thinking about if you're exhibiting signs of low testosterone, including decreasing muscle mass, decreased sex drive, and low energy levels.
Both supplements have organic components that have been shown in studies to support testosterone production and advance different health advantages. They both also have a money-back guarantee, so you can test them out risk-free to see whether they're right for you.
TestoPrime and Prime Male can take different amounts of time to start working with different people. That's because it depends on a variety of variables, including age, food, exercise habits, and general health. The majority of users begin to experience the effects of these testosterone boosters within a few weeks of beginning regular use. It's important to remember that these supplements do not work instantly and are not a magic cure. For these supplements to be as effective as possible, a good diet and exercise regimen also needs to be followed.
By optimizing your hormone levels, TestoPrime and Prime Male may help you gain more strength. The hormone testosterone is essential for increasing strength and muscle mass. Men may have diminished strength and muscle mass as well as other unpleasant symptoms when their testosterone levels are low.
TestoPrime and Prime Male may be able to help you in gaining more power and muscular mass by raising your testosterone levels. But this won't happen simply by taking the supplement. You also need to be doing resistance training in order to bring about an adaptive stress response in the body that leads to a strength increase.
Both TestoPrime and Prime Male deserve their reputations as leading natural testosterone boosters. The goal of this article, though, has been to determine which one is the best.
After a careful analysis of the ingredients, claimed benefits, dosages, reviews, and price, it has become clear to us that TestoPrime is the better product. It contains more of what might be considered the core 'T' boosting ingredients and in greater dosages. This isn't to say that Prime Male isn't a good product. It is, but TestoPrime is just that little bit better!
